LocalTime is an immutable time class representing a time
without a time zone.
 LocalTime implements the ReadablePartial interface. To do this, the interface methods focus on the key fields - HourOfDay, MinuteOfHour, SecondOfMinute and MillisOfSecond. However, all time fields may in fact be queried.
 Calculations on LocalTime are performed using a Chronology. This chronology will be set internally to be in the UTC time zone for all calculations. 
Each individual field can be queried in two ways:

getHourOfDay()
hourOfDay().get()

The second technique also provides access to other useful methods on the
field:

numeric value
text value
short text value
maximum/minimum values
add/subtract
set
rounding


LocalTime is thread-safe and immutable, provided that the Chronology is as well.
All standard Chronology classes supplied are thread-safe and immutable.

Constructs a LocalTime from a java.util.Calendar
using exactly the same field values.

Each field is queried from the Calendar and assigned to the LocalTime.
This is useful if you have been using the Calendar as a local time,
ignoring the zone.

One advantage of this method is that this method is unaffected if the
version of the time zone data differs between the JDK and Joda-Time.
That is because the local field values are transferred, calculated using
the JDK time zone data and without using the Joda-Time time zone data.

This factory method ignores the type of the calendar and always
creates a LocalTime with ISO chronology. It is expected that you
will only pass in instances of GregorianCalendar however
this is not validated.

LocalTime.Property binds a LocalTime to a DateTimeField allowing
powerful datetime functionality to be easily accessed.

The simplest use of this class is as an alternative get method, here used to
get the minute '30'.
LocalTime dt = new LocalTime(12, 30);
int year = dt.minuteOfHour().get();


Methods are also provided that allow time modification. These return
new instances of LocalTime - they do not modify the original. The example
below yields two independent immutable date objects 2 hours apart.
LocalTime dt1230 = new LocalTime(12, 30);
LocalTime dt1430 = dt1230.hourOfDay().setCopy(14);


LocalTime.Property itself is thread-safe and immutable, as well as the
LocalTime being operated on.
